## Description
|
||
<section id='description'>
|
||
Let Sn be an integer sequence produced with the following pseudo-random number generator:
|
||
S0
|
||
=
|
||
290797
|
||
Sn+1
|
||
=
|
||
Sn2 mod 50515093
|
||
|
||
|
||
|
||
Let A(i, j) be the minimum of the numbers Si, Si+1, ... , Sj for i ≤ j.
|
||
Let M(N) = ΣA(i, j) for 1 ≤ i ≤ j ≤ N.
|
||
We can verify that M(10) = 432256955 and M(10 000) = 3264567774119.
|
||
|
||
|
||
Find M(2 000 000 000).
